I application im npr-n ba,

To all whom t may concern Be it known that I, RoEnr LSToKEs,

a citizen of the United States, residing at Cincinnati, in the county oi' Hamilton and State of Ohio, have invented new and -t1seful Improvements in Tank FloatVaive Mechanism, of which th'e following is a specification.

My invention relates to the flushing tanks of toilet rooms, and more particularly 'to improvements in float valves themselves and the means of opening and closing them. Une remarkabiie difference between this inventionrand the one 'reviousb7 filed by me having Serial No. 8?'5332 is found iin the fact that, in ithis invention, there .is but one 'ii'oat valve, While in that o Serial No. 814,332 there 'may be a 'pluraiity of ii'oat vaives.

'p e object of my invention `is to aiord a single :float valve mechanism in "the single naat valve can be `opened 'and closed asv noise'lessly fas that of a 'plurality ol" fi-oat valves. I accomplish .this object b means off the mechansm hereinafter desem ed and aflso iglstrated ,by e accompanying 'drawin^gs ,jin which 1i he reference charaters .rep-

ed to sW-i'rrg .freely. 1 is a Washer inter- Venih'g between the tank A and the Water cup 'C on the inside of the tank, and 2 is a similar Washer intervening between said tank and the nut 2', said Washers being adapted lto prevent the sai-d Vtank around the inlet pipe B. The nut 2 is aiaed to bind all of the aforesaid members mly together. 3 is the Hoet valve d Wl'iich 'is mounted the iioat valve 8 which has in its upper surface a circular recessi'nto Which is tight-fitted a washer, prefer `y of Eleather, which washer is adapted to 'engage the circular boss 8 and cut ofi" the How off Water through the opening 9 into the downward extension 14 of the inlet pipe 12 is a collar, loosely-fitted onto the upper end osaid 'oat valve stem and is ada te'd to prevent the Water escaping through t e opening 12 from spurting out of the top of said tank. 4 is Ja horizontally positioned Support eXtending across the bottom of said to the inner sides of which its ends are fatta led, said support, through an opening in ich said stern passes, being adapted to, Steady and give direction to said ioat valve'stem its movement up and down. 5 is a lever ulcrumed on :the screw 6 which end rovi" said lever, which end is adapted to receive said float valve stem. l0 is the barbed endof said hook J, which hook when ing sleeve 27, which sleeve is adapted to prevext said barbed end from Wearing said pin i'ntvvo. 1'5 are lthe threads, by means of which said cap is 4screwed onto `said Water cup, and '6 are 'the threads, by means of which the lower en of said Water stand pipe is screwed (in-to sai Water cup, said pipe communicating directly with the inside cavit, of said ou lt'fis the supporting stem of -ghe weight 1g. 18 's a horizontally positioned support exte iig across the mouth ofsaid pipe to the inner surface o f 'which 'its ends are attached,

support, through an opening in which ,being adapted to stead' sai seing Stampa p and give direction to said stem rui ,its upvvar an oivnward mpv ent. Said weight 18 to said oat valve whether the escape of Water from J and is adapted to receive the impact of the end of the screw 22, 23 and 23' are screws passing through the stem H, the lower end ofscrew 23 is adapted to engage the circular enlargement QG of the lever F, first in the descent of the float ball 25 and first, also, in the upward movement of said lever on account of the actuating force of lever 5 and weight 18 on said stem 8. 28 and 29 are the two sides of the saddle-bearing supporting said float ball stem.

Having thus described my invention in detail and by illustrations, I will now describe it as a working mechanism. The position of the several members of my invention as illustrated in Fig. l indicates that the iioat valve is closed and the tank is full of water. (,)n the opening of the iush valve of the tank, the float ball 25 begins to fall and continuing in its downward movement, the lower ond of screw 23 engages the enlarged end QG of lever I?, first and then the lower end of screw 23 engages said lever which lever in its .lownward movement enga es the upper end of tlul float valve stem 3 ancopens the llfcat valve 8 which permits the water to ilov; through the opening 9 and into the downward extension 14 of the inlet pipe B, out of which extension said water passes into the tank A. YVhen lever F reaches the lowest point of its depression, the barbed end 10 thereof engages the pin 11 thereby locking said lever down. The flushing valve is now closed. The water now continues to iiow into the tank as aforesaid and said float ball begins to rise. 1When said float ball in its ascent reaches the point where the threaded end of screw 22 engages and sufciently presses upon the enlarged end 21 of the hook J, the barbed end l0 of said hook is disengaged from the pin 11, and said lever rises. Simultaneously with the disengaging of said barbed end of said hook and the rising of said lever, weight 18 falls and presses the end 7 of the lever 5 up against the float valve 8 and closes it. At the time of the closing of said float valve, the rapid moving water in the water cup C is suddenly turned aside and flowing into the stand pipe I, suddenly strikes the elastic air confined within said stand pipe, and is thereby prevented from suddenly7 striking the inside surface of said water cup and from producing the noise that would 'inevitably result therefrom. Thus we come back to the point of beginning.

Having thus described my invention in detail, by illustrations and as a working mechanism, what I claim is 1. In a float valve mechanism, a water cup having a water inlet, a hollow cap therefor having alined ports in its upper and lower walls, the ort in the lower Wall servin as an outlet fJor said water cup, a depen ing boss surrounding said port, a rod vertically positioned within said cap, the upper portion of'which rod extends through the ports in the walls of the cap, said rod carrying a recessed valve thereon inside the cap, which valve has a tight fitted washer in the recess thereof, and which valve is adapted to seat upon the depending boss and control the flow of water throu h the port which said boss surrounds, an a slidable collar upon said upper end outside the cup adapted to prevent the spurting of an water which mig-ht leak through the port m the cap and around the rod, a pipe communicating with the inside of the cap and closed at its upper end, said pipe forming an air chamber, a weight positioned in said air chamber, a lever fulcrumed midway its ends positioned one end of which wholly within the cup, lever engages a recessed valve and the other end of which acts as a support for the said weight which thus tends to close the valve. 2. In a tank float valve mechanism and in combination; a water cup; a hollow cap therefor; a short standard extending integrally upward from one portion of said cap and a longer standard extending integrally upward from another portion of said cap, said standards having preferably bifurcated free ends; a lever positioned horizontally above said cap, said lever having a circular enlargement on one end and a` perforation through the other, said perforated end engaging the bifurcated end of said short standard, said lever having also a perforation through the central portion thereof; a pin extending horizontally from said cap and at approximately right angles to the vertical plane of said lever, said pin having thereon a revolving sleeve; a lever having a rectangular enlargement on one end, a hook on the other and a centrally positioned perforation therethrough, said lever being vertically positioned, said perforation being adapted to engage said centrally positioned perforation through said horizontally positioned lever by means of a screw passing through said perforations, said vertically positioned lever being adapted to oscillate on said screw, and said hook when depressed being adapted to engage said pin; a lioat; a stem therefor having the end portion opposite said ball bent at approximately right angles to said stem, the end of said end portion having a. circular enlar ement, said stein having a perforation theret rough near said bent end thereof, said bent end ortion of said stem being positioned within the bifurcated upper end of said longer standard to which it is secured by means of a screw passing through said stem perforations and a perforation through the bifurcated upper end of said standard, said stem having also three set-screwspassing therethrough, two through said stem between said perforation therethrough andsaid ball and the othcil through the enlarged end thereof, the threaded end of said first mentioned screws being adapted to engage the enlarged end or' said horizontally positioned lever and the threaded end of said second mentioned screw being adapted to engage the enlarged end of said vertically positioned lever, and discngage the barbed end thereof from said pin.

S. ln a tank lloat valve mechanism, the combination of a water cup having an inlet ivater chamber and a discharge water chamber divided by a ported diaphragm, a valve adapted to close the port in the diaphragm, a stem upon the valve, a weight adapted to carry the valve toward the diaphragm, a lever fulcrumed upon the Water cup and engaging the stem of the valve, a Hoat stem Fulcrumed adjacent to the lever, means adapted to engage the lever to carry it to an operative position holding the valve from the diaphragm, a catch for the lever adapted to lock automatically when the lever assumes its operative position, and a projection upon the float stem adapted to unlock the catch upon the upward movement of the float stem.
